MACHINE FOR SCREW-THREADING WIRE.

SPECIFICATION forming part of Letters Patent No. 310,817, dated January 13, 1885.

Application filed March 24, 1884. (No model.)

To aZZ whom it may concern..- I

Be it known that I, LoUIs GoDDU, of Winchester, county of Middlesex, State of Massachusetts, have invented an Improvement in Machines for Screw-Threading WVire, of which the following description, in connection with the accompanying drawings, is a specification like letters on the drawings representing like parts.

The object of my invention is to produce a machine in which the wire to be threaded is rotated, a stationary cutter or threading-tool acting upon the wire during its passage from one spool to another.

The especial features in which my invention consist will be specifically set forth in the Figure 1 is a sideelevation, partially broken out, of a machine embodying my invention; Fig. 2, a top view of Fig, 1, also broken out at places; Fig. 3, a left-hand end view of Fig. 1; Fig. 4, a section of Fig. 1 on the line 00,- Fig. 5, a section of Fig. 1 on the line as; Fig. 6, a section thereof on the line 00 and Fig. 7 an enlarged detail showing the wire-rest and cutting or threading tool.

The frame-work A has bearings a b c to sustain the various parts. Bearings a a receive a sleeve or hollow shaft, d, which is rotated by a belt, d, on a pulley, d. The sleeve d at one end has ears d, which receive between them the spool d, carrying the wire 6 to be screwthreaded, the spool being supported on a pin or bolt, e. Theopposite or inner end of the sleeve d, having a screw-threaded projection, 6 (see Fig. 1,) has screwed upon it the rollercarrying head B, which is provided with a feedingroller, f, grooved and serrated, as shown in Figs. 1 and 5.

(Jo-operating with the roller f is a second like roller, f, the journals of which are held by the boxes 2,.attached to the said head by the screws 3. Theshaft of the feeding-roller fhas fast upon one end of it a worm-gear, ftwhich is engaged and rotated by the worm on the worm-shaftf. The shaft of the roller f has at one end a pinion, g, which engages a pinion, 9, fast on the shaft of the feed-roller f. The worm-shaft f 3 has fast upon one end of it a pinion, 4, (see Figs. 1 and 4,) the teeth of which engage the teeth of the stationary ring gear h, fixed with relation to the bearing a.

receives through it a spindle, 0, with which it is connected firmly by the nut r, screwed upon the threaded end of the said spindle, the interior of the hub of the drum resting against a shoulder on the spindle, as bestshown in Fig. 6. The spindle 0 has placed upon it loosely a worm-gear, 0 which is engaged and driven by a worm on a shaft, m, having a pinion, m, which is engaged and driven by the teeth of the stationary ring-gear 0 fast to the bearing 0. The gear 0 is driven at a certain speed by the shaft of, and drives the drum D frictionally through a friction washer, r", placed between the end of the hub of the drum and the side of the pinion, whereby as the mass of wire on the drum increases the drum and spindle 0 will slip or fall behind the speed of rotation of the worin-pinion 0 The cam-hub p is placed loosely upon the spindle o, and is driven therein at a reduced speed through the threaded portion 9 of the spindle 0,which engages along gear, 8, on a short shaft in the head D, the said shaft having an attached bevel-gear, 7, which engages teeth on and drives the cam 12, so that the latter by'its groove which receives the pin p of the wiredistributing arm 2 effects the vibration of the said distributor always at a speed proportional to that of the drum. The shaft 22 has a thread at one end, which receives a nut, 25, the latter retaining the said shaft in the head D against longitudinal motion, the length of the threaded part of the shaft 22 being such as to leave sufiicient space between the nut 25 and the bevel-gear 7 to permit the free rotation of the shaft 22. The outer end of the cam 12 is chambered (see Figs. 2 and 6) to receive a nut, 26, which, screwed upon a threaded portion of the spindle i0, governs the force of the pressure exerted between the drum and the friction-disk, pinion 0 and cam p. The wire e,

after passing from the rollers ff, enters a notch of wire rest or guide, t, held adjustably in place by a block, t, and screw 16 and just beyond the said rest the wire is acted upon by a cutting or threading tool, t held adjustably in place by abloclqni", and screw 12.

The invention described will thread wire on its passage from one to another spool, both spools being revolved and rotated to deliver and wind up the material.

I claim 1. In a machine for screw-threading wire, a spool to hold the wire to be threaded, a spool to receive the wire after it is threaded, combined with a stationary cutting or threading tool, and with means to revolve both spools to rotate the wire in contact with the said tool, substantially as described.

. 2. The hollow rotating spindle, the wireholding spool connected therewith, the head and its feeding-rollers, and the stationary gear 71, combined with the shaft f and gearing to rotate the said feeding-rollers, substantially as described.

3. In a machine for screw-threading wire, the shaft m, its attached head, the spindle 0, the loose gear 0 thereon, and means to rotate it,co1nbined with the frictionallvdriven wirereceiving spool placed on the said spindle, the parts operating substantially as and for the purpose described.

4. In a machine for threading wire,the shaft m, its attached head, the spindle o, the loose gear 0 thereon, means to rotate it, the wirereceiving spool placed on the said spindle and driven frictionally, as described, combined with the cam 10, mounted loosely on the said spindle, the wire-distributer or arm, and with means between the said spindle and cam to rotate the latter, substantially as described.

5. The hollow spindle or shaft (1, the spool d, rotated with it, the head B, feeding mechanism, and means to actuate the latter, combined with the shaft on, its head D, the spindle 0, carried in the said head, means to rotate it, and the spool D the material e from the spool (1" being wound upon the spool D substantially as described.

6. The hollow spindle d, its attached spool, the head, the feeding mechanism, means to actuate the latter, the wire-rest and threadingtool, and the shaft m, its attached head D, the spindle 0 therein, the spool D, and means to rotate the spindle 0 and the said spool, combined with means to rotate the spindle cl and shaft m, substantially as described.

7. The spindle 0,provided with the threaded portion 9, the drum attached to it, the wormpinion o", and cam loose on the said spindle, a friction-disk between the said pinion and druin,and means to rotate the said pinion,coinbined with gearing between the spindle and cam to rotate the latter at a given relative speed as compared with that of the drum, and with a distribnter to distribute the said wire on the drum from flange to flange, substair tially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
